Hasn't happened...venting

So my boyfriend and I have been having unprotected sex for the last year. I am 25 he is 27 we have talked about that we would both be happy if we got pregnant but it hasn't happened. So we had another conversation and really want to start "trying". I'm just already discouraged that it hasn't happened yet. He did tell me he has a low sperm count that he found out about a few years ago. Hoping for the best. Any advice would be appreciated.
